hacky way to run and mange a bunch of processes

server.sh

#!/bin/bash
old_mongo_pid=`ps auxww | grep mongod | egrep -v grep | awk '{print $2}'`
# Start mongo and memcache if not running
ps aux | grep mongod | grep -v grep || mongod &
#ps aux | grep memcached | grep -v grep || memcached & pids="$pids $!"

if [ "$old_mongo_pid" == "" ]
then
    echo "mongo wasnt running"
    sleep 1
    pids="`ps auxww | grep mongod | egrep -v grep | awk '{print $2}'` $pids"
fi
echo $pids

cd content
rackup -s thin & pids="$pids $!"
rails server thin & pids="$pids $!"
trap "echo caught signal;kill -15 $pids;sleep 1;kill $pids; exit" 1 2 3 6 15
